Applications

Viledon fan-filter units with HEPA filters are used for intake and recirculating air filtration of cleanrooms and air-conditioning systems with ultra-stringent requirements for clean air quality and sterility. Housing The housing consists of an extruded, anodized aluminum frame and a deep-drawn plastic plenum cast in an airtight configuration, with an integrated fan, a connection for measuring the raw-gas concentration and operating pressure drop, plus an operating light. The removable diffusor, fixed in place with tension closures, is made of perforated aluminum sheeting. Filter elements Associated filter elements such as Viledon HEPA/ULPA filters of filter classes H 14 to U 15 with aluminum frames can be ordered separately (see table for technical data). A prefilter panel is optional available.

Features

  • ƒƒThe Fan is driven by an AC motor (230 V, 50 – 60 Hz single-phase, 1.2 A/0.28 kW).
  • ƒThe integrated electronic control system is equipped with a main switch and a heat protection.
  • ƒƒThe noise level amounts to < 75 dB (A) at maximum performance at a distance of 1.5 m below the filter element.
  • ƒƒThe outflow velocity amounts to max. 0.6 m/s and depends on the filter efficiency involved.
  • ƒƒA clamping system allows a tool-free installation of a prefilter.
